ATTORNEY United States Patent 6 The present invention relates toimprovements in shades for incandescent lamps and more particularlypertains to such a device formed of a plurality of sectorshaped plateswhich are relatively flat and readily assembled into a frusto-pyramidalshape lamp shade.

An object of the invention is to provide a plurality of relatively flatplates which may be readily manufactured and shipped in relatively smallflat packages and which may be readily connected to each. other andmounted on the socket for an incandescent bulb so as to provide a shadefor the lamp.

A more specific object of the invention resides in providing integralhooks along one edge of the sector-shaped plates which are adapted toenter slots in the side of an adjacent sector-shaped plate so that aseries of such connected plates will form a frusto-pyramidal shapeassembly which may be readily assembled and mounted on a socket or thelike for a lamp bulb. 7

Other objects and features of the 'invention will be more apparent asthe present disclosure proceeds and upon consideration ofv theaccompanying drawings and the following detailed description wherein anexemplary embodiment of the invention is disclosed.

In the drawings:

Fig. 1 is a side elevational view of, a lamp shade exhibiting theinvention and mounted on an incandescent bulb socket.

Fig. 2 is a side elevational view of one of the sector- 77 of Fig. 5.

The present invention is directed to a lamp shade formed of a pluralityof sector-shaped plates which may be stored in flat relationship andthereby. conveniently packaged for distribution through the customarymarketing channels. The plates. are so shaped and formed that they maybe readily assembled by a customer and mounted on a socket or the likefor a lamp.

In carrying out the invention a plurality of plates, such as shown at 10in Fig. 3, are stamped or otherwise cut from sheet-material such asmetal and preferably aluminum. The aluminum may be of the anodized typewith the color provided on the upper face 11 of the plates so that theunder surface remains bright and serves as reflecting means for thelight'waves emitted by the bulb 12. Any suitable number of plates 10 maybe employed in providing a complete lamp shade and in the embodimentillustrated eight of the sector-shaped plates are employed with theradial edges displaced from each other by approximately forty-fivedegrees.

In forming the plates a series of hook-shaped ele- 'ments '14 are formedintegral with the plate along one of the radial edges thereof. It willbe noted that these 3Q manipulation of the tab 23 and the shoulder 28provides ice hook-shaped elements are depressed below the plane of theassociated plate 10 as will be apparent from a consideration of Figs. 4and 7. The hook-shaped elements 14 are provided with a notch 16 which isformed by a tip portion 17 on each of the hook-shaped elements. Anynumber of hooks may be provided along one radial edge of each plate 10and in the embodiment illustrated three of such elements are provided.

The opposite edge of each plate carries a lip 18 which is formedintegral with the plate. This lip 18 lies in a plane parallel with themain portion of the plate 10 but is depressed below the plane thereof adistance approximately equal to two thicknesses of theplate 10. In otherwords, the surface 19 of the lip 18 as shown in Fig. 4 is spaced twicethe thickness of the plate 10 below the upper surface 11. Such anarrangement provides a substantially right angle wall 21 of thesheet-material between the plate 10 and the lip 18. A plurality ofopenings or slots 22 (Fig. 4) are provided in the wall portion 21. Theseslots 22 are so placed as to receive'the hook-shaped elements 14 carriedby the adjacent sectorshaped plate. Thus in assembling the plates into acomplete lamp shade the hook-shaped elements 14 are introduced into theslots 22 and the hooks 14 are moved outward with respect to the slots22. The tip portion 17 thereby extend along the inner face of the wallportion 21 and hold the two plates in connected relationship.

Each lip 18. is provided with a tab 23 as shown particularly in Fig. 3.After the hook elements 14 have been properly introduced into the slots22 with the tips 17 lying behind the wall portion 21 the tabs 23 arebent upwardly and outwardly and thereafter downwardly to overlie theface portion 11 (Figs. land 6) of the adjacent plate. The tabs, 23 incooperation with the hook elements prevent relative endwise movement ofone plate 10 relative to the other and accordingly prevent inadvertentdis-' connection of one plate element relative to the other. The tabs 23may be bent to the position illustrated in Fig. 6 by the fingers or anysimple tool.

Each of the sector-shaped plates is provided with an extension 26 whichmay be formed integral with the plate during the stamping operation.These extensions are preferably of less width than the inner end of theplate so as to provide for shoulders 27 and 28 which facilitate the anabutment for the tab 23 of anadjacent plate when these tabs are bent tothe positions shown in Figs. 1 and 6. The extensions 26 may be bent inan arcuate shape as shown in Figs. 1, 5 and 6. The sheet-material whilebe ing relatively stifi is, nevertheless, flexible to such an extentthat the extensions 26 may be bent to form means for resilientlygripping the periphery of a lamp socket '28 such as shown in Fig. 1. Anannular elastic member 29 such as a helical spring may be employedembracing the bent extensions 26 and holding the lamp shade in positionon a lamp socket.

The structural features of the one type of lamp shade have beendescribed but it will be understood that changes may be made in thedimensions of the plates and the number to provide lamp shades of sizesother than that disclosed and having a greater or less number ofsectorshaped elements. The manner of assembling the plates into. acomplete lamp shade will be apparent from the description as hereinaboveset forth and the device provides means for shading the direct raysemitted by the lamp bulb 12 and also reflecting some of these raystowards an areav which is to be lighted. The plates 10 may be readilystamped in mass production methods and assembled in flat juxtaposedrelationship to thereby occupy a minimum of space for packing andshipment. The platesmay be readily assembled by a layman or customer andreadily attached to a lamp bulb socket.

While the invention has been described with reference to particularstructural details with reference to the manner in which thesector-shaped plates are adapted to be connected to each other and withregard to the manner in which the shade is mounted on the lamp socket itwill be appreciated that changes may be made in the construction ofthese parts. Such modifications and others involving the generalorganization may be made Without departing from the spirit and scope ofthe invention as set forth in the appended claims. 7
